NJU6053 Datasheet White Led Driver

Manufacturer: New Japan Radio

Overview: Preliminary www.DataSheet4U.com NJU6053 PRELIMINARY White LED Driver with Automatic Dimming Control !

General Description

The NJU6053 is a white LED driver with an automatic dimming control.

It contains an output driver, a PWM controller, a luminance sensor control (power supply for sensor & A/D converter), a step-up DC/DC converter, a serial interface, etc.

The NJU6053 can turn three independent lighting circuits on/off separately or simultaneously with instruction.

Key Features

  • # Drives up to 12 white LEDs (4 series x 3 parallels) # Controls 3 outputs separately VSW = 18.0V(Max), IOUT = 40mA # Built-in PWM Dimming Control (Selectable 8 out of 64 steps) # Built-in Luminance Sensor Control (Power Supply for Sensor & A/D converter) (No MPU-access required after initial setting) # Built-in Temperature Compensation Circuit to Suppress the Characteristic Degradation of LEDs # Uses Small Inductor and Capacitors # 1.8V to 3.6V Operating Voltage for Logic Circuits (VDDL) # 3.0V.
